What Causes Difficulty In Swallowing While Jogging?

I am currently jogging 3-5 times per week. I have been trying to take it slow as I have Sarcoidosis. I am not receiving any treatment for this condition as I have been asymptomatic. I am otherwise, a completely healthy 35 year old female. The last few days I have been having difficulty swallowing while jogging. WHen I stop and walk for a few minutes the problem resulves. Is this normal reaction to stressing the body or sign of intolerance to this level of activity?
